Updating ODM stanzas for system iSCSI devices
Updating the Object Data Manager (ODM) stanzas for the Storwize® V3500 iSCSI devices requires that you follow certain guidelines.
Before you begin
An interim fix is available to update the AIX® ODM stanzas to recognize iSCSI Storwize V3500 volumes.
Ensure that you have installed the official PTFs. The following website provides information about the available PTFs:
When you install the interim fix package, the AIX host can
recognize iSCSI Storwize V3500
volumes. The Storwize V3500
volumes are shown with the following attributes in Figure 1 for lsdev -C -1
hdisk1.
